If people click more than one radio buttons, then show all the text that compare with the radio's value. I can now show the text that compare with only one radio button's value, but if I click more than one radio buttons, it still shows the text that I select at first time. 

For example, in this case:  JSFiddle If I click "apple", it shows "apple apple" that's correct, but if I click more than one buttons like "apple" and "banana", it should shows "apple apple banana", but it didn't, how to achieve that goal? Thx
